listview设置行高

listview本身是没有办法设置行高的，需要借助imagelist;

ImageList iList = new ImageList();
iList.ImageSize = new Size(1, 30);//宽度和高度值必须大于等于1且不超过256
listView1.SmallImageList = iList;

listview header添加边框、背景色

private void listView_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    e.Graphics.FillRectangle(Brushes.LightBlue, e.Bounds);
    e.DrawText();
    using (Pen p1 = new Pen(Color.FromArgb(227, 227, 227), 1))
    {
        e.Graphics.DrawLine(p1, e.Bounds.X + e.Bounds.Width, e.Bounds.Y, e.Bounds.X + e.Bounds.Width, e.Bounds.Y + e.Bounds.Height);
        e.Graphics.DrawLine(p1, e.Bounds.X, e.Bounds.Y, e.Bounds.X + e.Bounds.Width, e.Bounds.Y);
        e.Graphics.DrawLine(p1, e.Bounds.X, e.Bounds.Y + e.Bounds.Height - 1, e.Bounds.X + e.Bounds.Width, e.Bounds.Y + e.Bounds.Height - 1);
    }
}

如果用imagelist修改了行高，listView_DrawColumnHeader也要改

private void listView_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    Rectangle r = new Rectangle();
    r.X = e.Bounds.X + 1;
    r.Y = e.Bounds.Y;
    r.Height = e.Bounds.Height;
    r.Width = e.Bounds.Width;
    e.Graphics.FillRectangle(Brushes.WhiteSmoke, r);
    e.DrawText();
    using (Pen p1 = new Pen(Color.FromArgb(227, 227, 227), 1))
    {
        e.Graphics.DrawLine(p1, e.Bounds.X + e.Bounds.Width, e.Bounds.Y + 1, e.Bounds.X + e.Bounds.Width, e.Bounds.Y + e.Bounds.Height - 2);
        e.Graphics.DrawLine(p1, e.Bounds.X, e.Bounds.Y, e.Bounds.X + e.Bounds.Width, e.Bounds.Y);
        e.Graphics.DrawLine(p1, e.Bounds.X, e.Bounds.Y + e.Bounds.Height - 1, e.Bounds.X + e.Bounds.Width, e.Bounds.Y + e.Bounds.Height - 1);
    }
}
